COAL-CHUTE.

'To all wit/172F216 7mm concern:

Be it known that I, JAMES MqTnrees, it

Morenci, in the county of Len'awee and State of Michigan, have invented certain new and useful Improvements in Coahflhutes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying and to the figures of reference marked thereon, which form a part of this specification.

' Myinvention relates-to chutes of the class adapted to remain permanently secured wit 'n a window opening or casing and to combine both a closure for such opening and a chute fordireoting coal, wood, or the like therethrough.

The object of my invention is the provision of a simplified and improved construction of chute of this class, having a removable hopper portion, which is adapted to be entirely inolosed within the chute when the door thereof is closed, placed in position to serve as a hopper for the chuteop ening,'or removed there mm to convert it into a chute for wood or other bulky objects.

A further object of my invention is the provision, in combination with a chute, of a closure or door therefor which is adapted when raised to automatically ock itself in elevated position and to serve as a shield or protection for the portion of'the framework or wall immediately abbve the opening therein while coal or other matter is being discharged. within the chute.

The invention is fully described'in the following specification and shown in the accompanying drawings, in which- Figure 1 is a perspective view of my improved chute in open position. Fig. 2 is a vertical secured therein inv similar section and in closed. position, and Fig. 3 is a verticalseclion of a frame wall having the chute mounted in an opening therein with the door elevated and the hopper removed.

. Referring to the drawings, 1 re resents the wall of a building, which may e of brick, stone, wood, or other suitable construction and provided with an opening or window through which coal, wood, or other matter may he discl'iarged,

Specification of Letters Patent.

Application filed May23, 1906. Serial No. 518,286.

v sistsof the rectangular citizen of the United States, and a resident of section of a brick wall with my chute.

Patented Oct. 16, 1906.

my invention conframe or casing member 2, which is of suitable size to fit around the margin of the opening provided in the wall 1 and is formed at its inner edge with the rearwardly-projecting. flange 3, Which fits Within the opening. Riveted or otherwise The device comprising secured to this flange is the inner end of the chute portion 4, WhlCh extends inwardly and downwardly at an angle to give it the desired slant and terminates at or,near the inner side of the Wall, as shown.

1 At the upper portion of the frame 2 are can'ym' the bearin -pins 6, to which the ears 7 o f the door 8 ire hinged. The pins 6 project Within slots 9 in the ears 7, thus enabling the door when raised substantially to vertical position to drop down slightly relative to said pins, so that the outer ends of the ears 7 coa'ct with the frame and revent a lowering of the door, as shown in igs. land 3. Pivoted to an car 10 near the lower inner edge of the door 8 is a hook 1 1, which is adapted when the door is closed to engage with the inner edge of the contiguous portion of the flange 3 or with a ledge formed thereon, as s 1OWI1 in Fig. 2, thus preventin an unlocking of the door from without the uilding.

I Normally inclosed. within the chute 4'is what may be termed a hopper 12. hopper comprises the triangular side portions 13 and the curved bottom portion'M, the former being pivot-ed at their apexes or uper ends to the opposite side flanges of the ame 2, near the tops thereof, as at 15. To enable the hopper to be readily removed from the pivots 15, the receiving-bearings therein are formed in L shape, with one end opening without the hopper side, as shown at 16: his hopper is retained in inclosed position by the door 8 when closed, as shown in Fig. 2, and is retained in open position to act as a hopper for the chute by the provision adjacent the lower edge thereof of one or more lugs or spurs 17, which are positioned to coact with the lower ortion of the frame 2, shown in Fig. 1.. he slotted bearings 16 permit the hopper to be raised. to enable these lugs or spurs to pass over thecoacting frame ortion.

lNhlle I have shown and described for the purpose of illustration a particular form of chute and hopper therefor, I do not wish to l restrict myself to this construction, as nuformed 'the two outwardly-projecting lugs 5, v

This 1 merous modifications thereof will be apparent to one skilled in the art.

With my construction of chute the hopper may be drawn out to the position as shown in Fig. 1 to adapt the chute for the reception of ooah'potatoes, or other like matter, or it may be entirely removed from the chute, as shown in Fig. 3, when it is desired to discharge wood or the like therethrough. The raising of the door above the chute-openim also forms an advantageous feature thereo as the woodwork or wall immediately above the opening is thereby protected from flying member pivoted within and adjacent the top particles of the matter being handled. Having thus described my invention, what I claimas new, and desire to secure by Letters Patent, is

1. The combination with a chute, of a hopp aced in operative or inoperative position. relative thereto.

2. The combination with a chute, of a hop:-

per. portion removably pivoted therein adjacent its mouth and adapted to be placed in operative or inoperative position relative thereto. 3. The combination with a chute, of a triangular-shaped hopper removably pivoted thereinandadapted to be entirely inclosed therein or drawn out to act as a hopper for the mouth of the chute.

4. The combination with a chute, of a door hinged to normally and a member pivoted within the chute and adapted to be placed in inclosed position when the door is closed and be drawn out to act as a hopper therefor when the door is inopen position.

he combination with a chute, of a door i and a hopper each havin separate pivotal connection therewith,

and the latter being per. ortion pivoted thereto and adapted to close the mouth thereo locked in inoperative position therein by a closing of the door.

6. The combination with a chute, of a door adapted to be'elevated above the mouth thereof-when open, and a member normally inclosed within the chute and adapted to be drawn out to 'act as a hopper for its mouth when the door is open.

7. The combination with a chute, of a door pivoted above its mouth and having means associated with its pivot for automatically loc'kin it in elevated position.

8.- he combination with a chute, of a of the mouth thereof, said member being adapted to be swung outwardly'relative to the chute to act as a hopper therefor and provided with slotted bearings having one end open to permit a removal of the member from its pivot.

9. In combination, a chute, a door hinged at the top of the chute-mouth and havingslotted bearing-ears for the purpose "described, a hook on the door for locking within the mouth of the chute when .the door is closed, and a hopper comprising triangular sideportions and a curved base portion conmeeting the side portionsand provided with spurs for coacting with the lower outer portion of the chute-frame when the hopper isin open position, said side portions being pivoted within the chute-mouth and having open slotted bearings, substantially as described.

r In testimony whereof I have hereuntov signed my name to this specification in the presence of two subscribing witnesses.
